Hydrophone Preamplifier Optimization. Prediction of Hydrophone Self- Noise by a Noise Model

Abstract

This report presents analysis of the self-noise which determines the threshold pressure level in hydrophone designs. The noise present in the acoustic sensor, coupling network, and preamplifier input stage are represented by an equivalent circuit noise model. A model provides an effective method to predict in advance of sensor-preamplifier construction the noise levels expected for a specific design.
